Modern buildings are sealed more tightly to conserve energy. Unfortunately, this seals in mold, pollen, bacteria and other pollutants. Since the EPA ranks indoor air pollution among the top five environmental risks to public health, there is reason to be concerned.

Ventilation systems replace a portion of stale indoor air with fresh outdoor air, reducing energy loss in the process. Air exchangers for instance, let users manually or automatically adjust the fresh air flow. The units retain energy used to heat or cool, saving money on utility bills. Ultraviolet air treatment systems or UV Lamps are designed to prevent mold spore growth on air conditioning coils. This technology, used for decades in water treatment, helps reduce allergic reactions to mold while enhancing overall air quality.

Air cleaners offer an effective way to remove up to 94 percent of the particles - dust, pollens, pet dander, plant spores, fungi, bacteria, tobacco smoke, etc. - from the air that passes through the home. York offers both electronic and media air cleaners. Whole-house humidifiers replenish the much-needed moisture in the air inside. This is important because warm, dry air absorbs moisture from everything around it, and breathing this air can be difficult.
